The issue you are facing:
I receive two kind of warnings:
Your *web server* is *not* properly set up to resolve “/.well-known/caldav”..
and same for webinfo,cardav, etc.
And the second warning is
The “*X-Content-Type-Options* ” *HTTP* header is *not* configured to equal to “*nosniff* ”
Is this the first time you've seen this error? _(Y/N)_:
The output of your config.php file in /path/to/nextcloud
(make sure you remove any identifiable information!):

My nextcloud installation is in /var/www/html/cloud.
I already added in /var/www/html/.htaccess the following lines, as suggested in other topic:
Header set X-Content-Type-Options "nosniff"
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^\.well-known/carddav /cloud/remote.php/dav [R=301,L]
RewriteRule ^\.well-known/caldav /cloud/remote.php/dav [R=301,L]
RewriteRule ^\.well-known/webfinger /cloud/index.php/.well-known/webfinger [R=301,L]
RewriteRule ^\.well-known/nodeinfo /cloud/index.php/.well-known/nodeinfo [R=301,L]
</IfModule>
My nextcloud server is reached by a caddy reverse proxy. This is the Caddyfile:
(https_header) {
header {
Strict-Transport-Security "max-age=31536000; includeSubdomains"
X-XSS-Protection "1; mode=block"
X-Content-Type-Options "nosniff"
X-Frame-Options "SAMEORIGIN"
Referrer-Policy "same-origin"
}
}
https://nuc.labahouse.it {
import https_header
reverse_proxy http://10.0.0.5
rewrite /.well-known/carddav /remote.php/dav
rewrite /.well-known/caldav /remote.php/dav
reverse_proxy {$NEXTCLOUD_HOST:localhost}
tls XXXXXXXXXXX.it {
dns cloudflare yyyyyyyyy
}
}
I can’t understand what is wrong in my configuration…
